Hi,

Thanks. I had got some question.
(1) Let said i got a nmos as per attached and i need to do a dc sweep of both VGS and VDS and plot I-V Curves.I had created the circuit, but how should i plot the I-V curves that have Vgs = 1V, Vgs = 2V and Vgs = 3V?And from the curve, how do i extract the values of Vt, K, λ and γ?

(2) And also if i create a common source amplifer, how do i bias Vdc so that i can get 100uA drain current and how do i go about plotting the graph of Vout verus Vdc and the gain verus vdc?

Please advise and thanks a lot!
